Title: Railroad crossing obstacle detecting device
Inventor: ISHII MOTOAKI
IPC: B61L29/00
Filed: 1990-10-04
Abstract: PURPOSE:To reduce the setting number of light emitters and light receivers and to secure a good detection by setting a light emitter and a light receiver at one side of a railroad cressing, while setting a light relay to receive the light emitted from the light emitter and to transmit the light to the light receiver, at the other side of the crossing. CONSTITUTION:The majority of the light radiated from a light emitter S1 provided at one side of a railroad crossing 1 to a light relay 2 provided at the other side of the crossing 1 is received and condensed by the receiver/condenser lens 10 of the light relay 2, and then injected in an optical fiber cable 11 from one end side. The incident light to the optical fiber cable 11 is injected to a luminous lens 12 from the other end side, and transmitted to a light receiver R2 provided at the emitter S1 side of the crossing 1, and received and condensed by the receiver/condenser lens 16 of the receiver R2. Since the light is relayed in such a way, two receivers R2 and two emitters S1 used in the conventional way are now not necessary to provide, but only one receiver and one emitter are used. Furthermore, the light quantity received and condensed by the receiver/ condenser lens 10 of the light relay 2 is increased.

Title: Automobile control device provided with tachometer register
Inventor: TANNO MITSUAKI
IPC: B60W10/06
Filed: 1987-10-21
Abstract: PURPOSE:To make it possible to measure the rotational speeds of several high speed rotating elements by storing precise periods of (n) pulses in a register with the use of a second counter for determining a measuring period and a control circuit, by calculating a rotational speed with interruption at every substantial set measuring period. CONSTITUTION:Each time when a detection pulse from a rotary element rises up, an increment of the content of, for example, a first counter 508 in a rotational speed measuring register is carried out. Meanwhile, a second counter 500A continuously counts clock pulses, and when it overflows, data on a measuring period setting register 504 is set. Simultaneously, a control circuit 510 holes the contents of both counters 508, 500A on registers 509, 502, respectively, with the timing of an input pulse from the next rotating element and a MPU 502 calculates a rotational speed per unit time from a pulse number (n) on the register 509 and a pulse period on the register 502 in association with an interruption demand signal. Thus it is possible to measure a rotational speed with a high degree of accuracy, and further, it is possible to shorten the process time of a microprocessor, thereby it is possible to measure several high speed rotating elements.

Title: Method and device for calking and joining metal plate
Inventor: OKAMOTO TOSHIO
IPC: B21D28/10
Filed: 1991-09-18
Abstract: PURPOSE:To easily and efficiently join by calking the superposed part of two metal plates with respect to formed article from metal plates by a roll forming mill. CONSTITUTION:The superposed part 11 of the metal plates 1, 2 is passed through between a projection roll 15 having a projection blade 17 and a receiver roll 16 having a receiving groove 18. The superposed part 11 of the metal plates is lanced and simultaneously pushed in; and the part A between the notched lines is upset and extended. The width of the receiving groove 18 is wider than the width of the projection blade 17 by the portion of a shearing clearance, and therefore, the part A between the lanced lines is expanded in width though slightly. In this case, the side wall of the receiving groove 18 is gnawed by the part A between the lanced lines, but as the receiving groove 18 is provided on the roll, the part A between the notched lines is easily taken out of the receiving groove 18. By the expansion of the width of the part A between the notched lines, the two metal plates 1, 2 are joined. Thus, calking to join metal plates is performed without a complex mechanism such as allowing the side wall to widely open on the side of a die hole.

Title: Ceramic composition for low-pressure molding
Inventor: HASHIMOTO SEIJI
IPC: C04B35/622
Filed: 1992-10-07
Abstract: PURPOSE:To facilitate the handling of a ceramic molding made of the subject composition and to improve the dimensional accuracy of the ceramic sintered body by increasing the strength of the ceramic molding while reducing the content of the solid added to the composition as a gelling agent to a level as low as possible and preventing cracks of the molding from generating at the time of dewaxing. CONSTITUTION:This ceramic composition for low-pressure molding is produced by adding as a modifier an inorganic alkali or alkaline earth metal salt, the aqueous solution of which shows a pH >7, to a slurry comprising a ceramic powder, an organic solvent, a dispersant and a gelling agent. The gel strength of the composition is increased by using this modifier, and therefore, the sufficient gel strength can be attained without increasing the gelling agent, i.e., at a lower solid content level. Thus, the stable ceramic molding can be obtained.
